Certigna Root CA

Certigna Root CA is a root CA certificate operated by Certigna (RSA 4096, valid until 2033-10-01, SHA-256 D48D3D23). As of the latest CCADB data it is trusted for TLS server authentication by 2 of 4 major root stores: Chrome, Microsoft.

Chrome stops trusting TLS certificates under this root whose SCTs are dated after 2026-06-14 (sct_not_after). The CCADB lists no EV policy OID for Certigna Root CA.

"Trusted for TLS" means the store includes the root with the server-authentication trust bit (Mozilla "Websites", Apple serverAuth, Microsoft Server Authentication EKU). Microsoft "NotBefore" means only certificates issued before a cutoff date are still trusted. "Constrained" means the store applies extra restrictions.

Intermediate CAs issued by this root

The CCADB lists 12 intermediate CA certificates signed directly by Certigna Root CA: 7 currently valid, 0 expired and 5 revoked (revoked includes those whose parent was revoked).

Showing 12 of 12: valid certificates first, newest first. Each name links to its crt.sh entry by SHA-256; an arrow marks a cross-certificate for another root on this site.

Cross-signed versions

1 certificate(s) in the CCADB have the same subject and public key as Certigna Root CA but a different issuer. A server can send one of them so that clients which trust the issuing root, but not Certigna Root CA, can still build a chain.

None of the valid intermediates under this root lists an OCSP responder.

What happens when it expires

Certigna Root CA is valid until 2033-10-01, about 6.9 years after this data snapshot (2026-11-10). From that day, browsers and operating systems that check trust-anchor expiry stop accepting chains that end at this root, so any certificate that can only chain to it fails validation. Android is a known exception: it does not enforce the expiry date of trust anchors. Root programs can stop trusting it before it expires: Chrome 2026-06-14.

Check whether your device trusts it

Each platform keeps its own root store. The commands below look up Certigna Root CA by common name (Certigna Root CA) or fingerprint. The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.

macOS (Apple store: Not included)

Search the system roots keychain by common name. -Z prints the SHA-256 hash, which must match the fingerprint on the last line.

security find-certificate -a -c "Certigna Root CA" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: D48D3D23EEDB50A459E55197601C27774B9D7B18C94D5A059511A10250B93168

Windows (Microsoft store: Included · Trusted for TLS)

Windows identifies roots by SHA-1 thumbprint. It installs third-party roots on demand through Automatic Root Certificates Update, so "not found" can also mean the root has not been needed yet; certutil -generateSSTFromWU roots.sst downloads Microsoft's full list.

certutil -verifystore Root 2D0D5214FF9EAD9924017420476E6C852727F543

Linux (ca-certificates follows Mozilla: Included)

Debian, Ubuntu, Fedora and RHEL build their ca-certificates package from Mozilla's root store. Use trust list on p11-kit systems, or search the PEM bundle on Debian and Ubuntu.

# Fedora / RHEL / Arch (p11-kit)
trust list --filter=ca-anchors | grep -iF -A2 "Certigna Root CA"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "Certigna Root CA"

Java

Java ships its own cacerts keystore; JDK 9 and later accept -cacerts and the default store password is changeit. Search for the SHA-256 fingerprint in colon form.

keytool -list -cacerts -storepass changeit | grep -i "D4:8D:3D:23:EE:DB:50:A4:59:E5:51:97:60:1C:27:77:4B:9D:7B:18:C9:4D:5A:05:95:11:A1:02:50:B9:31:68"

Android

Android's system store is maintained by Google separately from the four CCADB stores above. Open Settings → Security & privacy → More security settings → Encryption & credentials → Trusted credentials → System (menu names vary by vendor and version) and look for Dhimyotis → Certigna Root CA.

Which root does my site chain to?

List the chain your server sends and compare the last issuer with this root; the fingerprint check confirms a local copy.
